CHARLES ROBERT, OF HOLCOMBE, WISCONSIN.

FLY-TRAP.

Specification of Letters Patent.

Patented Dec. 15, 1908.

Application filed. September 8, 1908. Serial No. 452,034.

To all whom it may concern:

Be it known that I, CHARLES ROBERT, a citizen of the United States,residing at Holcombe, in the county of Chippewa and State of Wisconsin,have invented certain new and useful Improvements in Fly-Traps, of whichthe following is a specification.

The object of this invention is to provide a simple contrivance adaptedto be readily supported upon a window frame and so constructed as toform a trap for insects such as flies.

The invention involves advantageous features of construction in thistype of devices, the desirability of which will appear more fullyhereinafter.

For a full understanding of the invention, reference is to be had to thefollowing detail description and the accompanying drawings, in whichFigure 1 is a front elevation of a window showing a trap embodying theinvention in operative position; Fig. 2 is a vertical sectional viewshowing the device arranged as in Fig. 1; Fig. 8 is a longitudinalsectional view through the trap the slidable end piece being shown infull lines in the position thereof before placing the trap on thewindow, and in dotted lines in the position assumed when the trap isoperative for the purposes of the invention, and Fig. 4 is a transversesectional view of the device.

Throughout the following detail description and on the several figuresof the drawings, similar parts are referred to by like referencecharacters.

The invention is very simple in form so that it can be manufacturedcheaply and will therefore meet with a large demand. S ecificallydescribing the invention and re erring particularly to the drawings thenumeral 1 designates the window frame in which are mounted the usualsashes 2. The device comprising the invention is preferably arranged atthe upper portion of the window frame 1 transversely thereof and isdetachable when mounted in operative position. As is Well known it iscommon for flies to crawl upwardly upon the ane of a window sash andhaving in fnind tlie above the trap com rising the invention isconstructed pecu 'arly. The trap comprises a body 3 preferably ofsomewhat horizontal form and made preferabl of fine mesh Wire screen, orsimilar materia. The body 3 is so formed that its longitudinal edgesoverlap and are spaced apart to provide an entrance or mouth for thetrap as shown at 4. The longitudinal edges of the trap body 3 arereinforced by metal strips 5 and 6, the strip 5 being secured to theinner edge of the screen body 3 while the strip 6 is of U-form andapplied to the outer edge of said body. The inner edge of the screenbody 3 at the entrance 4 is projected beyond the strip 5 in order toprovide a number of fine wire fingers or projections 5 and in likemanner the outer edge of the body 3 is folded upon itself by beingturned inwardly, the folded portion secured between the sides of the U-shaped strip 6, and the extreme edge of the material projected inwardlyby the strip 6 to provide projections or guard fingers 6 cooperatingwith the fingers or projections 5 to prevent flies from escaping fromthe trap after they have walked into the same through the entrance 4.The projections 6 curve inwardly toward the projections 5.

The opposite ends of the body 3 are closed by end pieces or caps 7 and8, the cap 7 having a short flange receiving an end of the body 2 whilethe cap 8 has a long flange to receive the adjacent end of the body 3.Both caps 7 and 8 are provided with openings 9 to receive supportingpins 10 applied to the window frame and arranged in spaced relation. Thepins 10 may be nails driven into the opposite sides of the frame 1 andin horizontal positions.

In placing the invention in operative position the caps 7 and 8 areapplied to the ends of the body 3 in the manner shown in Fig. 8. Thetrap is then elevated and the pins 10 at one side of the frame 1 engagein the openings 9 of the end piece or cap 7. This having been done theend piece or cap 8 is located adjacent to the pins 10 on the oppositeside of the frame 1 but spaced therefrom as shown in Fig. 3. By outwardsliding movement of the cap 8, however, the adjacent pins 10 will passthrough the openings 9 in said cap and the trap will be supported firmlyin a horizontal position and with the entrance 4 thereof close to thepane of the upper sash 2 and in a position permittin flies to readilywalk into the trap and be t us caught. Catches 11 are provided on theflanges of the caps 7 and 8 to engage in openings in the screen orreticulated body 3 to hold the caps positively connected with the bodywhen it is arranged in operative position as shown in Fig. 1. To removethe trap in order to empty the same of insects the catch 11 of cap 8 isdisengaged from the body 3, said cap moved inwardly away from the pins10 and thus by disengaging the cap 7 from its pins 10 the device isdetached in an evident manner. Vertical spacing members 12 space thelongitudinal edges of the body 3.

Having thus described the invention, what is claimed as new, is:

In combination with a Window frame, an insect trap comprising a hollowbody provided between its ends with an entrance or mouth, supportingmembers applied to the frame, end caps for the body of the trap engagedwith the supporting members aforesaid to hold the trap in operativeposition, one of said end caps being movable on the body to permit ofattachment and detachment of the trap from the frame, and catches forconnecting the end caps and body.

In testimony whereof I affix my signature in presence of two Witnesses.
